Bath have agreed a deal to sign Scotland international David Denton from Edinburgh, subject to a medical.
The 25-year-old, capped 32 times by his country, is likely to come in as a direct replacement for Sam Burgess, who left the club to re-join South Sydney Rabbitohs following a dismal World Cup performance with England.
Denton joined Edinburgh in 2010 and went on to make 79 appearances, scoring eight tries for the club, helping them to reach last season's European Rugby Challenge Cup final, where they were defeated by Gloucester.
He impressed for Scotland during the World Cup last month and featured in all but one of their group matches as well as the quarter-final defeat to Australia.
"I've had an incredible six years at Edinburgh," Denton said.
"It's been the hardest decision I've ever made, as I am going to miss the club, but I am really looking forward to an opportunity to play at one of the premier clubs in Europe."
Bath have agreed to buy out the final six months of Denton's contract in order to bring him to The Recreation Ground.
Edinburgh Rugby head coach Alan Solomons added: "David has made an invaluable contribution to Edinburgh, both on and off the field, and I'm sad to see him go, both as his coach and personally.
"He's been a model professional. His powerful performances and work ethic have been outstanding, and his commitment to the club over the years has been an inspiration to many of our younger players and supporters.
"I know this wasn't an easy decision for him and I, and everyone at the club, wish him all the very best for the future."
Scottish Rugby chief executive Mark Dodson said: "This move represents an excellent opportunity for David to gain new experience in another playing environment.
"It came out of the blue, and while it wasn't an easy decision, we weren't going to stand in the way. Edinburgh Rugby is well covered in the back-row department and this gives young, local talent like Jamie Ritchie, Magnus Bradbury and Hamish Watson further opportunities to play.
"David has been an excellent player and ambassador for Edinburgh and we look forward to him continuing to be available for Scotland national team duties, when selected."
